What should a security guard do when witnessing a crime in progress?

When a security guard witnesses a crime in progress, the best course of action is to call law enforcement and avoid intervening unless necessary for safety. This approach prioritizes the safety of both the guard and the public. Engaging directly with suspects can be dangerous, as the outcome may escalate into a violent confrontation, potentially putting the guard at risk as well as innocent bystanders.

By notifying law enforcement, the guard ensures that trained professionals can respond appropriately to the situation, handling it according to the law and established protocols. This response also helps to document the crime, allowing authorities to take action based on factual evidence, which can lead to better outcomes for investigations and prosecutions.

In addition, remaining at a safe distance allows the guard to observe and provide valuable information to law enforcement, such as descriptions of the suspects or their vehicle, which can be crucial for apprehending the criminals.

This response is in stark contrast to the other options, which either suggest taking unnecessary risks or completely overlooking the incident, which could result in harm to individuals involved or the potential for the crime to escalate further.
